AbstractResults of calculations on the economic potential for alternative (low input, sustainable) farming systems in a small grain-row crop region of the Northern Plains are reported. Two sets of alternative farming systems, in which no chemical fertilizers or herbicides are used, are compared with various conventional and reduced till systems. In Farming Systems Study I (FSS1), an alternative rotation consisting of oats, alfalfa, soybeans, and corn is compared with conventional and ridge till rotation systems composed of corn, soybeans, and spring wheat. In Farming Systems Study II (FSS2), three systems with an emphasis on small grains are compared. An alternative system rotation consisting of oats, sweet clover, soybeans, and spring wheat is compared with conventional and minimum till rotation systems comprised of soybeans, spring wheat, and barley. Results of baseline economic analyses show that alternative farming systems can be competitive with more conventional systems in at least some situations. The alternative systems entail markedly lower direct costs, and the alternative system in FSS2 has approximately the same net returns as the comparable conventional and minimum till systems. The FSS1 alternative system has positive but somewhat lower net returns than the comparable conventional and ridge till systems. Sensitivity analyses were conducted with alternative system crop yields, chemical fertilizer and herbicide prices, and varying assumptions about future Federal farm program support levels and acreage set aside requirements. The yield sensitivity analyses show that one alternative farming system requires yields about 5–10 percent above those of the comparable conventional system to produce the same net returns. However, the other alternative system is competitive with a conventional system even with yields 5 percent lower. Analyses varying chemical fertilizer and herbicide prices reveal that the alternative farming system in FSS1 becomes competitive with more conventional systems when fertilizer and herbicide prices rise by 50 percent. The alternative farming system in FSS2 is already competitive at current fertilizer and herbicide prices. In some cases, sensitivity analyses with Federal farm program provisions indicate that reductions in farm program benefits increase the economic competitiveness of alternative farming systems. However, important exceptions occur. Results indicate that not only the level of future farm program benefits, but also the form of program provisions and compliance requirements, will affect the relative competitiveness of alternative farming systems.

Infiltration Techniques

AbstractQuantitative data are needed to understand how alternative farming practices affect surface infiltration of water and associated surface soil properties. We used a rainfall simulator, double ring infiltrometer, small single ring infiltrometers, and tension infiltrometers to measure water infiltration for Clarion loam (fine-loamy, mixed, mesic Typic Hapludoll) and for Webster silty clay loam (fine-loamy, mixed, mesic Typic Haplaquoll) soils located on a conventionally-managed and an alternatively-managed farm in central Iowa. Steady-state measurements suggested that infiltration rates were somewhat higher for the alternative farming system. Bulk densities were sometimes lower, and volume of large pores was a little higher for the alternative farming system. Small single rings were more reproducible than rainfall simulators or double ring infiltrometers, and data trends were the same as for rainfall simulators.

Organic Farming System

Excessive use of inorganic chemicals results in adverse impacts on land and plants. In the midst of the community, there is anxiety about the high content of pesticide residues in agricultural products. There is a need to develop alternative farming systems that are able to produce quantities and quality of healthy products in a sustainable manner. One agricultural system that supports the concept is the organic farming system. The basic principles of organic farming are: (1) Keeping the ecosystem healthy, (2) Applying the principle of efficiency to the cultivation system, (3) Conducting production activities with the concept of sustainable agriculture, (4) Producing pesticide-free products, and (6) Maintaining environmental sustainability. Food Crop Production Study Program Lampung State Polytechnic makes Organic Agriculture as one of the leading competencies for its graduates. The establishment of the Organic Agriculture Business Unit on campus will increase student competencies, foster entrepreneurship, be a place for competency internships, and as an independent source of income.

SUMMARYFor efficient utilisation of available farm resources and to increase the income per unit of land, seven integrated farming systems were developed and different combinations of crop, animal, fish and bird were evaluated at three locations of Eastern India, viz. Patna, Vaishali and Munger districts, to sustain productivity, profitability, employment generation and nutrient recycling for lowland situations from 2007–2008 to 2009–2010. Among the tested different Integrated Farming System (IFS) models, viz. (i) crop + fish + poultry, (ii) crop + fish + duck, (iii) crop + fish + goat, (iv) crop + fish + duck + goat, (v) crop + fish + cattle, (vi) crop + fish + mushroom and (vii) crop alone, crop + fish + cattle model recorded higher rice (Oryza sativa L.) grain equivalent yield (RGEY) (18.76 t/ha) than any other combinations, but in terms of economics, crop + fish + duck + goat model supersedes over all other combinations. The highest average net returns (USD 2655/yr) were recorded from crop + fish + duck + goat system over all other systems tested here. Higher average employment of 656 man-days/year were also recorded from crop + fish + duck + goat system because of better involvement of farm family labours throughout the year. Based on a sustainability index (SI) derived from different models, crop + fish + duck + goat system was found superior with a maximum sustainability for net returns (73.1%), apart from the addition of appreciable quantity of nitrogen, phosphorus and potassium into the system in the form of recycled animal and plant wastes. The wastes/by-products of crop/animals were used as input for another component to increase the nutrient efficiency at the farm level through nutrient recycling. Results on integration of different components with crop depending upon suitability and preferences were found encouraging, and to enhance the productivity, economic returns, generating employment for farm families and maintaining soil health of the farm, the crop + fish + duck + goat combination could be adopted in the eastern part of India than cultivating the crop alone on the same piece of land under irrigated condition. Addition of organic residues in the form of animal and plant wastes could also help in improving the soil-health and thereby productivity over a longer period of time with lesser environmental hazards. The livelihoods of small and marginal farmers could be improved by their adoption of IFS technologies on a larger scale, as they provide scope to employ more labour year-round.

Organically Grown

Organic farming standards do not allow addition of water-soluble fertilisers and therefore it is likely that growth of organically grown crops will be limited by nutrient availability. However, in marginal rainfall conditions, when growth in conventional systems is limited by water availability, yields of organically grown crops could be comparable with those conventionally grown. Similarly, micronutrient-efficient plant varieties could be expected to perform comparatively better under organic farming conditions than they do in conventional systems, when compared with micronutrient-inefficient varieties.In this study, biomass and grain production of wheat from certified organic farming systems were compared with neighbouring conventional farming systems in 'across the fence' field trials in 1 moderate and 2 marginal rainfall areas of South Australia. Wheat varieties compared included 2 old wheat varieties developed under relatively low-input conditions (Baroota Wonder and Dirk-48) and varieties shown to be micronutrient-efficient (Janz and Trident) and inefficient (Yallaroi).The organic farming systems produced significantly less biomass than the conventional farming systems at late tillering in both the moderate and marginal rainfall areas. Grain yield was variable, but significantly lower in the organic farming system for 11 of the 14 comparisons. None of the varieties showed an adaptive advantage for 1 farming system over the other. The relative yield of the organic system, compared with the conventional system, was not associated with rainfall.

The field experiment was conducted to study the integrated farming approach over conventional method of agriculture farming. An area of 5.6 ha of land was selected for the experimental trial involving twelve small and marginal farmers at village Chakramdas of Vaishali district in Bihar. The initial survey conducted to assess the farming practice and the economics of conventional farming over developed integrated farming systems (IFS). The crop equivalent yield (q/ha), net returns (Rs/ha) and the Benefit: Cost ratio was calculated both as per farmers practice and as per integrated farming approach. Crop + fish +duck +goat integration supersedes over all other integrations in terms of monetary returns (Rs. 1,07, 828/annum) with a sustainability index of 83.9 while in terms of RGEY, Crop + fish + cattle integration supersedes among other integrations (18.76t/ha) but due to more labour requirement it couldn't supersedes over crop + fish + duck + goat integration in economic terms. Under individual component goat rearing again supersedes over other enterprises with a B: C ratio of 2.7. Additional nutrient gain in terms of NPK was found highest with poultry upon nutrient recycling within the system.

Effects of soil fauna on soil quality are largely unknown. Our objective was to learn whether long-term soil management has significantly affected earthworm species and populations at two Iowa locations. Soil cores were collected in fall 1989, spring 1990, and fall 1990 from a long-term tillage study in Polk County, Iowa, involving monoculture of corn (Zea mays L.) with either no-tillage, fall disking, fall chisel plowing, or fall moldboard plowing. Species found were Lumbricus terrestris (L), Octolasion tyrtaeum (Savigny), Aporrectodea trapezoides (Duges), A. turgida (Eisen), and A. tuberculata (Eisen), with O. tyrtaeum dominant across all treatments. As the amount of tillage increased, the number of earthworms generally decreased. InBoone County, Iowa, we compared the populations of mature and immature earthworms and cocoons on two adjacent fields, one managed conventionally, the other managed with an alternative farming system for more than 20 years. The predominant species was A. tuberculata. Regardless of management practice, the most worms were found in Canisteo soil on the toeslope landscape position.

Total Productivity

The study was conducted to develop Integrated Farming Systems (IFS) model for limited irrigation situation. The land was earmarked for developing 1 ha. land for marginal/small farmers with crops, horticulture, fodders and animal components. This system resulted in total productivity of 41.4 t ha-1 yr-1 Rice Grain equivalent Yield (RGEY) along with employment generation of 830 man days. The net returns from 1 ha of crop + livestock (dairy and goat) + horticulture farming systems model was Rs. 2,17,336/-. Of this total net income, crop component including fodder comprised 27.74%, horticulture component comprised 4.41% and livestock unit shared 67.85%. Besides cash income, IFS generated employment for family labour. Recycling of bi-products from the livestock unit, sustains soil productivity.

Biodynamic Agriculture

The concerns regarding food security and safety, environmental challenges and resource scarcity remodel the prospects of agriculture. Therefore biodynamic farming as an alternative method for sustainable production becomes an object of growing scientific interest in the past 20 years. Biodynamic farming is one of the oldest organic systems and its roots could be found in the beginning of 20th century. Although the skepticism, biodynamic agriculture evolved over the years and nowadays is considered as an opportunity to address various environmental, social and economic issues. The aim of the paper is to introduce the concept and features of biodynamic agriculture and observe different case studies and surveys on the effect of this farming system upon yields, profitability and sustainability. The analysis is based on different research methods. The paper applies monographic, historical and comparative methods. The results indicate that biodynamic farms have higher soil quality, lower crop yields, and equal or greater net returns than conventional agricultural holdings. The long-term effect of biodynamic farming on the economic performance, however, needs further research and investigation. The studies prove that biodynamic agriculture is important alternative farming system that could provide answers to number of alarming questions associated with viability and sustainable development.

The study was conducted at Dingapota Haor under Mohongonj Upazila in Netrakona District during April 2011 to March 2012 to examine the profitability of individual farming systems namely crop-livestock-poultry–fishcatching (C-LP- FC), crop-livestock-fish catching-labour selling (C-L-FC-LS), fish catching– labour selling (FC-LS), crop-livestock (C-L), crop-livestock-fish catching (C-L-FC) and crop-livestock-poultry (C-L-P). A total of 60 farm households under six farming systems were selected that analyzed the level of input used in different enterprises. The results showed that the highest net return of C-L-FC farming system was Tk. 119214 and lowest for C-L-P farming system which was Tk. 25131.The estimated total costs of C-L-P-FC, C-L-FC-LS, C-L, C-L-FC and C-L-P farming systems were Tk. 287959, 304430, 62316, 255624, 322654 and Tk. 241354 respectively. Again for C-L-P-FC, C-L-FC-LS, FC-LS and C-L farming systems, the net returns were Tk. 66238, 107578, 74673 and 42967 respectively. Among the farming systems, C-L-FC produced the highest gross margin of Tk. 424859 and CL- P produced the lowest which was Tk. 266486. The benefit cost ratio of all the farming systems was more than 1 which indicates that all of these were profitable. The gross margin, net return and BCR for C-L-FC farming system was reasonably high and the system earned positive management income indicating that the farming systems were economically viable even under all possible full cost assumptions.
